Wiseco Mitsubishi 4G63 87.00 mm Bore 34.87 mm CH -9.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty engine builds. The 87.00 mm bore size is specific to certain Mitsubishi 4G63 engine configurations, and the compression height is set at 34.87 mm with a dish volume of -9.00 CC, which will affect your final compression ratio depending on your cylinder head volume.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal enhancements to ensure reliable performance under extreme conditions. The crown is also fully machined for accuracy. For improved durability and reduced friction, the piston skirts are treated with an ArmorGlide coating, which helps prevent seizure and quiets operation. The design also includes forced pin oiling to keep the wrist pin properly lubricated.

This set includes four pistons, complete with premium rings, ready for installation in your performance 4G63 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper fitment and assembly procedures.
